Charge after 9 p.m.
On Xcel’s default time-of-use plan, 5–9 p.m. weekdays is on-peak at about 2.7× off-peak. Scheduling your charger to start after 9 p.m. is free and saves real money over a year of driving.
Xcel has offered wiring rebates for home charging — reported up to $1,300, or $2,300 for income-qualified customers — tied to enrolling in an Xcel charging program. Confirm current terms before you count on it.
Your EV as a shutoff battery
A compatible EV with a bidirectional system can back up your home through a wildfire shutoff. Our bidirectional whole-home backup systems start around $19,000, and a large EV battery holds several times the energy of a home battery. It only works if your specific vehicle supports it.
